Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority of U.S. Provisional Application Ser. No. 60/101,822, filed Sep. 25, 1998, the subject matter of which is fully incorporated herein. This application also incorporates by reference U.S. Design application Ser. No. 29/096,196, filed Nov. 6, 1998.

FIELD OF THE INVENTION

This invention relates to an outdoor luminaire, in particular an outdoor luminaire having a housing adaptable to a plurality of interchangeable tops and a plurality of interchangeable light transmissive doors.

BACKGROUND OF THE INVENTION

Architects prefer to have the ability to ‘mix and match’ elements when designing so that the selection available is maximized and the lighting scheme can be coordinated throughout the structure and/or surrounding area. It is therefore desirable to have an interchangeable outdoor luminaire having a plurality of interchangeable tops and a plurality of interchangeable light transmissive doors.

SUMMARY OF THE INVENTION

An interchangeable outdoor luminaire includes a housing that has an open top and an open bottom to form a circular top rim and a circular bottom rim, respectively, a plurality of interchangeable tops each with an open top that forms a circular rim that matches the top rim of the housing, and a plurality of interchangeable light transmissive doors each with an open bottom that forms a circular rim that matches the bottom rim of the housing. The circular top rim of the housing has a stepped top edge. The circular bottom rim forms a circumferential recess with a stepped bottom edge. Each of the tops have the same circular rim with an annular flange having the same diameter. The annular flange of the tops has a slightly larger diameter than the circular top rim of the housing. The flange fits over the circular top rim of the housing to form an interface between the housing and the top.

The plurality of interchangeable light transmissive doors are each capable of being received into the circumferential recess of the bottom of the housing and each have the same circular rim with a circular outer edge. The circular outer edge of the door is spaced close to the bottom stepped edge of the housing to provide two closely spaced surfaces that facilitate joining the housing and the door. The circular outer edge has a slightly smaller diameter than the stepped bottom edge, thereby enabling the transmissive door to fit into the circumferential recess.

The plurality of interchangeable tops include a pyramidal top, a dome top, an up-light dome top with a decorative cast guard, and an up-light dome top. The plurality of interchangeable transmissive doors include a flat tempered glass, a round drop glass, a flat drop glass, and a tear drop acrylic. Any of the tops for the housing can be used with in conjunction with any of the light transmissive doors.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The drawings depict an outdoor luminaire which includes a number of interchangeable parts. As illustrated in FIG. 1, the luminaire includes a top 11, a housing 10; and a light transmissive door 12. The housing attaches to one of a number of different arm structures 100; examples of arm structures are illustrated in FIG. 5. The top and the door are shown in dashed lines because there are a number of different tops and doors that can be used with the same housing. Any of the tops 11 of FIG. 3 for the housing 10 can be used in conjunction with any of the light transmissive doors 12 of FIG. 4. Each of the tops 11 are configured to fit over the housing 10, and each of the light transmissive doors 12 are configured to be received under the housing 10.

FIGS. 2A and 2B show plan, side and cross-sectional views of the housing 10. The housing is open at the top and open at the bottom to form a circular top rim 16 and a circular bottom rim 18, respectively. The top 11 has an opening that forms a circular rim 19. Rim 19 fits over rim 16 to form an interface between housing 10 and top 11. The door 12 has a circular rim 21. Rim 21 fits into rim 18 to form an interface between housing 10 and door 12.

The circular top rim 16 has a stepped circumferential edge 14 to be received into the circular rim 19 of one of the tops 11 available for selection in constructing the luminaire. The circular bottom rim 18 of housing 10 has a circumferential recess 24 with a bottom stepped edge 26 that is dimensioned to receive the circular rim 21 of one of the light transmissive doors 12 available for selection in constructing the luminaire.

As shown in FIGS. 3A-3D, respectively, the top 11 is preferably one of a pyramidal top 25, a dome top 20, an up-light dome top with a decorative cast guard 30, and an up-light dome top 40. As shown in FIGS. 4A-4D, respectively, the light transmissive door 12 is preferably one of a flat tempered glass 50, a round drop glass 60, a flat drop glass 70, and a tear drop acrylic 80. As illustrated in FIG. 3A, the circular rim 19 of the pyramidal top 25 has a downwardly directed annular flange 28 with a diameter slightly larger than the stepped circumferential edge 14. The flange 28 fits over and interfaces with the stepped circumferential edge 14 as a result of the top being placed onto the housing. Similarly, in FIGS. 3B-3D, the circular rim 19 of the dome top 20, the up-light dome top with the decorative cast guard 30, and the up-light dome top 40 has a downwardly directed flange 22, 32, 42, respectively. Thus, each top 20, 30, 40 interchangeably fits onto housing 10 and interfaces with the housing 10 in the same manner as described above. See also FIG. 6A.

As shown in FIGS. 4A-4C, each door 12 has the circular rim 21 with a circular outer edge 15 that is of a slightly smaller diameter than the bottom stepped edge 26. The rim 21 is annular in shape. Flat tempered glass 50 extends across the annulus in the same plane as rim 21. Round drop glass 60 curves downwardly from rim 21 across the annulus. Flat drop glass 70 extends across the annulus in a plane below rim 21. Tear drop acrylic 80 curves downwardly from 21 across the annulus. The circular outer edge 15 of the door 12 is closely spaced to the bottom stepped edge 26 when received into the circumferential recess 24.

A reflector 17 is set in the housing 10 to reflect the light source in the housing and to produce different light patterns depending on the type of light transmissive door. (See FIG. 6B.) For example, the flat door directs the light and cuts it off at a certain angle, while the drop doors emit widely angled light.

A gasket seal 13 is placed between the door 12 and the housing 10, as shown in FIG. 6B, to seal the interior against dust, moisture, and bugs. The gasket seal 13 connects to the housing 10 at an edge of the reflector 17 near the bottom stepped edge 26.

A back portion of the circular rim 21 hingedly connects to a corresponding portion of the bottom stepped edge 26. The hinged connection allows easy access to the lighting fixture for repair and maintenance. Through a front latch (not shown), a front portion of the circular outer edge connects with a corresponding front portion of the bottom stepped edge. Preferably, the front latch is a thumb screw.

The dome top 20, and the pyramidal top 25 are preferably made of metal. The dome tops 30 and 40 are preferably made of plastic or glass so that there is illumination above the outdoor luminaire.

The top stepped edge 14 of the housing and the flange of the top form two closely spaced, relatively large surfaces with an angle therebetween, as shown in FIG. 6A. This interface facilitates joining the housing and the top by welding, bonding, or screwed connection. If the top is welded to the housing, as is preferable for the metal tops, the space between the top stepped edge and the flange is filled with weld material. If the glass or plastic up-light dome top is selected for a luminaire, the top is not welded to the housing because of the risk of breaking the glass or melting the plastic. Instead, the top is bonded to the housing by silicone or another compatible material. Alternatively, the top could be screwed to the housing so that the glass or plastic top can be easily replaced or maintained.

Although the present invention has been described and is illustrated with respect to various embodiments thereof, it is to be understood that it is not to be so limited, because changes and modifications may be made therein which are within the full intended scope of this invention as hereinafter claimed. For example, there are many other possible designs for the light transmissive door and for the tops, and each of these doors and tops can be designed with a housing interface that corresponds to the housing and can be coupled therewith.
